JAIVIES H. REMINGTONQOF WAUWA'IOSA, AND JOI-IN D. REMINGTON, OIE'lWAUKESHA, WISCONSIN, AND VOLNEY Gr. GRAHIT,` OF ROCKFOB-D, ILLINOISPULLEY HOUSING Application led January k30, 1930. Serial No. 424,620.

This invention relates to improvements in pulley housings. 4

One of the objects of our invention is the provision oit' a pulleyhousing which is particularly adapted to that class of pulleys supportedin window trames and over which the sash cord passes ior supporting thesash weight and window, wherein the pulley housing, the attaching plateand the guides for the sash cord are formed of a single piece ofmaterial. y A y Another object of our invention is the provision ot animproved housing for sash pulleys wherein vthe housing and componentparts are formed of asingle piece of material in order to provide for amore rigid and simple construction and for the purpose of reducing themanufacturing cost of this article, so that it can be placed on themarket andv sold at a very small cost.

A further object of our invention is the proy vision of a pulley housingof the above character formed of a singlepiece of material and whereinlaterallydisposed ribs are formed in the construction ot the housingadapted to Y snugly fit the mortise within the window iframe so as toprevent lateral movement on the part of the pulley housing, while the4sash cord is passing over the pulley, thus retaining the housing in itsrespective position so that the sash cordwill bemaintained in directalignment at all times.

A still further object of our invention is the provision of a pulleyhousing formed of a single piece of material, wherein the guiding hoodswhich direct the sash cord over the pulley are formed integral with thehousing and are so positioned as to permit the cord to be quickly andeasily passed around the pulley.

lith the above and other objects in view. the invention consists in thenovel features ot' construction, the combination and arrangement ofparts hereinafter more fully set forth, pointed out in the claim andshown in the accompanying drawings wherein:

Figure 1 is a vertical sectional view, taken through a windowr frame,illustrating the application of my improved pulley housing, with-thehousing disclosed in side elevation;

Figure 2 is a sectional view on the line Q-Q of Figure l;

'Figure 3 is a transverse section on the line In the lgeneralconstruction of window' frames, there is provided a longitudinal passagel, within the main portion of the trame 2', and this passage is closedby means of a cover board 23. Usually, in placing these sash pulleyswithin the frame, a mortise is cut through the cover plate 3 and thepulley housing mounted in the frame, and due to the fact that in cuttingthese openings, they are generally made a little bit larger than thepulley housing, and when the pulley is placed in position, it has atendencytoward lateral movement when the sash cord is passing over thepulley, and furthermore, with the usual construction of pulley housings,it is rather dithcult yto thread the cord over the pulley unlesssuitable Vguiding means is provided.

In the general construction of our improved one-piece housing, it willbe noted that the blank is stamped out in the form illustrated in Figure5, and the central portion ot the blade having its ends extended totoi-m the attaching means ,tor the housing when completed. One edge oithe blank is provided wit-h straight longitudinal portions l at eachside oi` the longitudinal center which terminates in a tab 2 anddirectly below this tab is another longitudinal portion 3 with a portionoi' the blank slit inwardly, as shown at et at the inner edge ot thelongitudinal por tion 3.

The edge opposite the longitudinal portion l of the blank isformed'rounding at the ends, as shown at 5, the purposefor which willhereinafter be more fully set forth'. In forming the main portion of thehousing, the side portions 6 and 6 of the blank are bent at right anglesto the central portion 7 which forms the attaching plate on the line 8and adjacent the attaching plate each side portion ofthe blank isJfolded upon itself to form the hollow rib 9 'which is adapted to .titsnugly Within the mortise 10 in the cover board 3. lt found desirable,these hollow ribs 9 may be formed With an inclined outer Wall, asillustrated in Figure 3, so that asubstantiallydriving .lit may be hadwhen placing the pulley housings in position, as shown in Figure 3.

The outer ends of the sections or side portions 6 and 6 are arcuatelycurved as Well as the edge opposite the longitudinal edge l to torniguides for the rope which passes over the pulley Within the housing, thetabs 2 being aressed inwardly, as shown at Figure l, to assist inguiding the rope over the pulley.

rThe ends and one side edge of each of the sections G and 6 are arrangedin abutting relation, as shown in Figures 3. and el, and form the sideWalls for the housing, aswell as one edge and one end, while thepartadjacent the longitudinal port-ion l is bent inwardly on the line ll toform opposite end Walls of the housing, thus leaving the ends of thecentral portion or tace plate extending beyond both ends of the housingand these ends are provided with perforations l2 to receive screwsy 13`which engage Wit-hin thecover board 3 for retaining the housing inposition within the mortise l0.

In order to provide a suitable guide for the Y sash cord upon theexterior of the cover board,

the central portion of the main blank which constitutes the face plateisprovided With an opening adjacent one end of the face plate and` a.portion of the material is drawn out from the faceplate to form t-henosepiece 14 the side Walls of which continue outwardly 'from one side ofthe hollow rib 9, asshovvn. The outline of the nose M tapers toward theclosed end thereof, as shown in Fi gure l. so as to cooperate with oneend orn the housing to provide av properly formed guide tor thesash cordWhen extended around t-he pulley.

rl`he pulley l5 ini the present instance is mounted upon atransverse pin16 which is normally provided With ahead on one end and in securing thepulley in position, the smooth end is insertedy through the oi'ienings1T iu the de walls of the housing and through the pulley and theotherend is then riveted, spun or enlarged in order to retain the pin inposition and securely hold the two side Walls of the housing againstyoutward movement.

The above construction provides a complete housing for a pulley, the,housing beingformed ot a single piece of, material and stamped to 'formthe outer line, as shown at Figure 5 and then quickly bent intoshape toprovide the complete housing as shown more clearly in Figures land il.In placing the pulley Within the'housingit can be inserted therein atone end beiore the longitudinal edges larel bent over intoabuttingrelation.

ltwill. be noted that. by providing the housing with a substantiallyhollow outstanding rib 9, as illustrated, this rib Will completely tillthe mortise l0 and prevents any lateral movement on the part of thehousing, While the sash oord is being passed therethrough over thepulley l5 and this tight. itting of the rib Within the mortise willassist in retaining the housing within the mortise. One of the essentialfeatures of our improved pulley housing is the 'fact that the entirehousing, 1ncluding the attaching plate 7 and the cord guides are formedot' a single piece of material.

lt will be apparent that a pulley housing` constructed in accordancewith the above, vvill not only reduce the. cost of manufacturing thepulley housings of this character, but the features incorporated in theforming o'l' the housing are greater and greatly facilitate not only themounting of the pulley housing, but the guiding or' the sash cord orchain through the housing and over the pulley, and 1t is believed that apulley housing constructed in accordance With the above will be farsuperior to any known pulley housings on the market at the present time.

qWhile We vhave shown and described the preferred embodiment of ourinvention, it Will be apparent that slight changes may be made in theconstruction When putting the invention into practice Without departingfrom the spirit of the same or the scope of the appended claim. Y

AvWe claim: f

A one-piece housing of the class described including a hollow body, anarcuate guide portion leading from one end of the. body, an i attachingplate at one side of the body, an arcuate nose piece integralwith theattac-hing ffl plate and laterally disposedv ribs onthe body Y adjacentthe' attaching plate. Y

In testimony that We claim the foregoing We have hereunto set. our handsat Milwaukee, in the county ofMilwaulcee and State of lisconsin.
